There has been alot of talk lately about adding grease to the knuckles. Here is an adapter that I talked about back on SOR and just thought it might make it easier for someone now. It's just a 3/8" pipe to 1/8" pipe bushing that can be purchased at any auto parts or hardware store. (Brass, black pipe, or galvanized, it does not matter. Just buy and install a 1/8" pipe grease zerk and you are in business.
The instructions are to remove the stock pipe plug (a 1/2" eight point socket will work), turn the adapter in HAND tight or very slightly with a wrench, add your grease, remove the adapter, reinstall the plug. The reason to not overtighten is twofold - there should be no pressure in the knuckle that you have to overcome, and, the taper of the 3/8" pipe threads is a little different than the stock plug. The stock plug starts off about .010" smaller than the adapter so you will only get about three threads on the adapter before it gets tight and you don't want to strip it.
Of course, maybe everyone already has one of these.
